In one of Damian Wayne's slowly growing collection of pet the dog moments, he tells his mother, Talia Al Ghul, that, despite being treated like a king and being given islands as birthday presents, being Robin and doing good has been the best thing in his relatively short life. And despite disparaging Dick's efforts at carrying the Bat-mantle at every turn, he does a 180 and interrupts when his mother tries to do the same:
Talia: Your father is gone. His former Boy Wonder is barely fit to wear his mentor's mantle and you... Damian: You're wrong. Dick Grayson is...
He then goes on to refuse her orders to turn his back on Dick and Alfred. Needless to say, Talia does not take this rejection well, and she not only disowns him but also declares him a foe. Damian has just given up everything he's known for an uncertain future and status with a still-absent father and a brother he still cannot admit he respects to his face. But he takes it like any real Batkid would.
Talia: ...I will permit you to leave with your circus boy in tow, but from now on, Damian, you are no longer welcome here. You may consider yourself an enemy of the house of Al Ghul. Damian: Very well. I hope I can be a worthy one, mother.
Damian learns that Bruce once lost a C-List criminal called Getwaway Genius, a super villain who has been off the radar for 10 years, and he finds it disappointing. Dick tells him the truth: the guy stole chemotherapy drugs so that he could stay alive long enough to see his daughter grow up, and Bruce let him get away, reimbursing the clinic the cost of the drugs, because "no child should have to grow up without their parents."
In Batman: Return of Bruce Wayne, after a long journey home to earth, to his time, Bruce dies ("clinically dead for two minutes"), and the forces of Darkseid and The Devil himself are fighting to make sure Bruce stays dead. Wonder Woman and Superman are doing everything within their power to revive him, but don't look very hopeful on the matter. Throughout the story, Bruce has lost his memories and merely been acting as Batman instinctively, but getting shocks of who he was, of himself as Bruce Wayne. Now, here within inches, even less than that, of his life, he remembers one thing. The moment he knew what he was going to do. He remembers, being broken, and beaten, and a bat flying through the window. And he remembers the bell. He remembers that despite his feelings of loneliness, and isolation, he's never been alone. Alfred, Dick, Jim, Barbara, Jason, Tim, Stephanie, Damian, Helena, Selina, Kate, Cassandra, Jean, Katherine, Renee, Vic, Charlotte, Holly, Rory, Boston, Harvey, Bette, Sasha, Julie, Vicki, Talia, Ace, Lucius, Slam, Oliver, Dinah, Barry, Wally, J'onn, Arthur, Hal, John, Kyle, Guy, Diana, Clark, Thomas and Martha, they've all been there for him. He's never been alone, he's been surrounded by people who care about him, and share his determination. He was never alone. He had help. Tim then, looking at Wonder Woman and Superman as if this was nothing, holds out the cape and cowl "I know how to bring him back. Tell him Gotham's in trouble. And tell him he'll need this." He purges the evil from him, and dons his costume, proclaiming to the heroes before him in utter awe "The Bells are still ringing. I'm not done yet. Not while Gotham City needs Batman. Not until the Night's Over"
Once he found Bruce was Back from the Dead, what was Damian's reaction? To worriedly ask if that means he & Dick can't be Batman & Robin anymore.
Towards the end, Damian tells Dick that he was always his favourite partner.
